7800 XT extremely low FPS on fresh install [Solved]

I have just freshly installed Arch using archlinux-2023.11.01-x86_64.iso

I see here that the 7800 XT performs well with the UNIGINE Superposition Benchmark.  However when I try on the same settings it I’m getting ~5fps

To rule out hardware / hardware config issues I installed Windows To Go on a flash drive.  This gives me benchmark results in a similar range to those in the Phoronix article.  My hardware seems good

    Interactive 3D benchmark: walk through a lab of a lone professor

  freesync is off on the monitor
  VT-d is off
  Same results with X11 / Wayland

cat  /sys/class/drm/card1/device/pp_dpm_mclk

0: 96Mhz *
1: 456Mhz 
2: 772Mhz 
3: 1218Mhz 

pp_dpm_mclk is stuck at 96Mhz / 465MHz depending on refresh rate.  This makes no difference to FPS

This is the GPU, I believe it only has a single BIOS : https://www.sapphiretech.com/en/consume … -16g-gddr6

AMD have temporarily removed OD for this card from kernel 6.5:  https://gitlab.freedesktop.org/drm/amd/ … te_2079945

I've read the section at the bottom of AMDGPU about MCLK being locked at 96Mhz.

cvt12 5120 1440 144 -b

# 5120x1440 @ 144.000 Hz Reduced Blank (CVT) field rate 144.000 Hz; hsync: 222.192 kHz; pclk: 1155.40 MHz
Modeline "5120x1440_144.00_rb2"  1155.40  5120 5128 5160 5200  1440 1529 1537 1543 +hsync -vsync

xrandr --newmode "MCLK-fix" 1155.40  5120 5128 5160 5200  1440 1529 1537 1543 +hsync -vsync

xrandr --addmode DisplayPort-0 "MCLK-fix"

Then I choose 144Mhz, as opposed to 143.98 that the system boots with, and I get this terrible mess

I also tried this with 85MHz and while I didn't get the same result I've not seen any increase in FPS and pp_dpm_mclk is still stuck

Thanks in advance for any suggestions

Re: 7800 XT extremely low FPS on fresh install [Solved]

Just tried cvt12 at 120MHz, which is one of the rates available when freesync is turned on in the monitor settings, and I got a very slightly different mess appear on screen

Re: 7800 XT extremely low FPS on fresh install [Solved]

Intel/Asus NUC systems tend to be heavily engineered to work well with intel hardware.

please enable the intel graphics as primary so the system will function as intel/Asus  designed it to do.

Once that's done post full lspci -k (run as user) and journal (run with root-rights) outputs.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?

Re: 7800 XT extremely low FPS on fresh install [Solved]

Next to that, what if you add

amdgpu.runpm=0 amdgpu.bapm=0 amdgpu.aspm=0 pcie_aspm=off

to the kernel paramters?
(+"amdgpu.dpm=0", but that'll likely prevent the system from booting?)

No outputs attached to the intel chip, you're running on xf86-video-amdgpu instead of eg. reverse-prime and an LG ultrawide that the driver complains about.
Do you have some other output (FullHD TV or so)?
Did the problem exist w/o xf86-video-amdgpu?

Re: 7800 XT extremely low FPS on fresh install [Solved]

Yes, I thought that was odd but I'm the one asking for help so...

Just booted with amdgpu.runpm=0 amdgpu.bapm=0 amdgpu.aspm=0 pcie_aspm=off amdgpu.dpm=0 and it hung, as predicted

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st  :  http://0x0.st/HtGK.txt

Booted again without amdgpu.dpm=0, no effect on FPS

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st  :  http://0x0.st/HtGP.txt

I will remove the added kernel parameters

I will also remove xf86-video-amdgpu and reboot with a spare 1080p monitor I have

Do I need something connected to the iGPU as well as the dGPU?

Booted with, after the other monitor, what seems like the smallest screen in the world

No effect on FPS

"possibly", see the caveat in https://wiki.archlinux.org/title/PRIME#Reverse_PRIME (though that's for reverse prime which you've not been running at any time, but god knows what the cause of that is)

Re: 7800 XT extremely low FPS on fresh install [Solved]

Bit confused.  Isn't Reverse PRIME for laptops?

Will the iGPU have to be plugged into a monitor?  I can plug it into the same monitor or I have an HDMI dummy plug I could use.  With the current BIOS settings if I plug it into my monitor I think the monitor will be iGPU powered and the AMD card will be second.  Although I do have PBP on this screen so I might be able use both together

Re: 7800 XT extremely low FPS on fresh install [Solved]

Reverse prime is for when you've outputs attached to the non-rendering device.
As mentioned, it does't /really/ fit your situation, but only because you had the IGP completely disabled and were running on the GPU in the other case.
You've not tried to run the server on the IGP (and attach the monitor there) and DRI_PRIME invoke the GPU only, have you?

Edit: for the reverse prime situation you'd need two outputs (one on the GPU, causing the reverse prime, one on the IGP to mitigate that weird bug - though I guess it's just a prime-sync related issue)

Re: 7800 XT extremely low FPS on fresh install [Solved]

Now I have HDMI from the iGPU and DP from the dGPU.  The iGPUS is set to default in the BIOS.  Both outputs are connected to the same monitor.

Using PBP I have set each output to one half each, splitting the display in two.  I have also set the display to 2560x1440 so that it functions as a standard 1440p screen, with large black bards on each side.  Both of these produce the same results.  Below I'm using Game >  Custom > Fullscreen Disabled > 720p because it's quick to load and allows me to view nvtop.

$ unigine-superposition

FPS fluctuates widely and extremely quickly between these approximate values, only by screenshotting am I able to actually read a number

$ DRI_PRIME=1 unigine-superposition

FPS is pretty steady at this.

The iGPU is arguably better than my 16GB AMD

With the dGPU running the benchmark I get the same stuck at 96Mhz etc etc

The PRIME link says I should install xf86-video-amdgpu.  I've just uninstalled that

sudo pacman -S xf86-video-amdgpu xf86-video-intel

Rebooting.....

Re: 7800 XT extremely low FPS on fresh install [Solved]

You could probably also have booted the multi-user.target (2nd link below), xf86-video-intel in particular is a really bad idea, but maybe (though I'm not holding my breath) xf86-video-amdgpu helps to power up the AMD GPU.

The problem is however that you're stuck in the low performance mode andfrom your other thread can't even manually get out of that.
That's be the amdgpu kernel module.

For a re-cap: have you tried not-gnome (eg. openbox)?
Have you tried to boost the GPU w/ a different testcase? Eg. https://archlinux.org/packages/extra/x86_64/vkmark/ ?

Re: 7800 XT extremely low FPS on fresh install [Solved]

I managed to get to cli but it hung when I did pacman -Rnsu so I went for chroot.  I do wonder if screen / tmux might have worked but I don't plan on finding out

vkmark - same results

Will try xf86-video-amdgpu again but it was installed before

I'm going to try SDDM and KDE Plasma

Please try a non-compositing WM and X11, for plasma, shift+alt+F12 toggles the compositor.

Re: 7800 XT extremely low FPS on fresh install [Solved]

grumpf.

Sanity check: you didn't forget to attach the dedicated power supply )6/8-pin connectors) and made sure that the GPU is seated in the PEG slot your board manual suggests?

The GPU works fine under a "Windows To Go" usb so I presume it's plugged in ok

Re: 7800 XT extremely low FPS on fresh install [Solved]

In the next few days I plan to put the GPU in my old machine and see if I can get anything different out of it to see if it's a BIOS / hardware issue.  However I built my old machine in February 2016 and I think it could have PCIe v3 so I'm not sure if this will be a good test or not

Re: 7800 XT extremely low FPS on fresh install [Solved]

The GPU works fine under a "Windows To Go" usb

So we can expect it to be not the HW.

Have you tested the behavior w/ some live distro? (grml, knoppix - maybe some webgl testcase, since it's probalby down to getting the GPU to clock up)

Re: 7800 XT extremely low FPS on fresh install [Solved]

Not the hardware unless there's something specific to this NUC.  I thought Intel's HW was pretty well supported under Linux.  Maybe I was wrong.  Officially Intel don't support Linux on this model but that's true of most hardware I've run Linux on

I've tried other distros on usb:

ubuntu-23.10.1-desktop-amd64.iso because it's closest to the setup that was used in the Phoronix article.  I also used this as a persistent usb in order to install the closed source drivers

ubuntu-22.04.3-desktop-amd64.iso as a persistent usb because that's the distro the closed source drivers are meant for

Garuda-dr460nized-gaming-linux-zen-230501.iso because I thought a gaming distro might have ironed out GPU issues

Nobara-38-GNOME-2023-08-29.iso because it ships with an older kernel - which I've since realised might have been a waste of time

Only Windows works

I'll try your suggestions
